TPS62740DSST Description

Short technical summary and product information.

The Texas Instruments TPS62740DSST is a highly efficient, ultra-low-power step-down (buck) DC/DC converter designed for low-power applications. It features a wide input voltage range from 2.2V to 5.5V and can deliver up to 300mA of output current. The device boasts a very low quiescent current of typically 360nA, making it ideal for battery-powered devices.

 

Key electrical specifications include selectable output voltages ranging from 1.8V to 3.3V in 100mV steps, a maximum switching frequency of 2MHz, and up to 90% efficiency at 10µA load. The TPS62740DSST utilizes Constant on-time (COT) and DCS-Control modes, along with features like Adaptive/Dynamic Voltage Scaling, Enable, Light Load Efficiency, Output discharge, and Synchronous Rectification.

 

Packaged in a compact 12-WSON (2x3 mm) with an exposed pad, this surface-mount device is optimized for small solution sizes. Its operating temperature range is -40°C to 85°C. The converter is suitable for applications requiring efficient power conversion in space-constrained designs, such as Bluetooth devices.
